Which database is responsible for storing published content in Sitecore?

The correct choice refers to the Web database, which is specifically designed to store published content in Sitecore. When content is published in Sitecore, it is moved from the Master database to the Web database. The Master database contains all content items, including those not yet published, while the Web database only holds the content that is currently available to end users on the live site. This separation ensures that the published site remains stable and that users interact solely with the content that has been approved for public access.

The Core database serves as a repository for Sitecore’s core data, such as user information and settings, but it does not store published website content. The Analytics database is used for storing data related to user interactions and tracking analytics, but it is not where the actual content for the site resides. Thus, the Web database is the dedicated storage for published items, making it the correct answer.
